asterisk users - Jun 2010 - Can sip clients connect with each other directly (RTP session) ?

Dear Asterisk friends,

     Please help me to clarify my doubt. After monitor SIP and RTP traffic with
Wireshark. I found that both SIP and RTP traffic between 2 sip clients  must be
passed through Asterisk.
 Is it possible that 2 sip clients connect with each other directly for RTP
session after sip session completed ?

Thank you,
Kamonwat

By default it is yes, however within a LAN environment you can usually
allow clients to re-invite directly between themselves.  Check the
"canreinvite" option out.//
